THE DIFFERENCE BETWEEN A BICYCLE HELMET AND A CLIMBING HELME Bicycle helmets  and  climbing helmets  are designed for different impact forces. Outside of their actual function, they do not offer the optimal protection.   Like cars, bicycle helmets are designed to collapse in a collision and absorb the energy of the impulse. And they only have to protect the head once – after the crash, they are broken. Usually, the danger is over after a bicycle accident and no further protection is needed.    Climbing helmets have to withstand several collisions. They are not designed like bicycle helmets and do not crumple in a collision. But they offer longer protection because you can’t stop climbing just because you had an accident. If you are in the middle of a climbing route and are hit on the head with a big stone, you still have to get down somehow. Climbing helmets are mainly designed to withstand several collisions. Especially from falling stone and not ...

BASICS Helmet  liners are made of foam that holds heat well. Human bodies use the head to radiate excess heat during exercise. Only a flow of air over the head can carry that heat out of the helmet, so ventilation becomes critical in hot weather, and is needed even in cold weather to carry moisture away. Back in the 1980’s a British university study found that the larger the front vents, the cooler the helmet. More recent research indicates that for optimal cooling the air also needs to be channeled to the exits, so the interior channels are important to taking in the most air possible through the front vents. In some designs air may even prematurely exit through the side or top vents before performing its cooling role, and researchers have covered some vents and actually improved cooling performance. Some air flows under the edges of the helmet if you have not sealed the edge against your head with fit pads. In short, the interaction of the vents and channels in directing th...

Standards Helmets must meet a defined standard to be certified for use in competition. Procedures vary from one nation to the next. However, as a general rule, the design standards are created by a standards organization that has  Helmet knowledge  of hazards in the field of activity, and then actual helmets are tested and certified by a separate Conformity assessment organization with testing expertise.   The  testing standards  in the United States and New Zealand are considered more rigorous than those in other nations. Independent testing in the United Kingdom in 2003 by the British Equestrian Trade Association found a number of “traditional” designs from the three most established and respected British manufacturers failed a series of tests intended to determine if a design provided proper protection in the event of a fall.   Conformity assessment Conformity assessment organizations that certify safety equipment perform some similar test...

WHAT IS FOAM Foam is an object formed by trapping pockets of gas in a liquid or solid. A bath sponge and the head on a glass of beer are examples of foams. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas. Soap foams are also known as suds. Solid foams can be closed-cell or open-cell. In closed-cell foam, the gas forms discrete pockets, each completely surrounded by the solid material. In open-cell foam, gas pockets connect to each other. A bath sponge is an example of an open-cell foam: water easily flows through the entire structure, displacing the air. A camping mat is an example of a closed-cell foam: gas pockets are sealed from each other so the mat cannot soak up water. Foams are examples of dispersed media. In general, gas is present, so it divides into gas bubbles of different sizes (i.e., the material is polydisperse)—separated by liquid regions that may form films, thinner and thinner when the liquid phase drain...

WHAT IS POLYCARBONATE Polycarbonate (PC) plastics are a naturally transparent amorphous thermoplastic. Although they are made commercially available in a variety of colors (perhaps translucent and perhaps not), the raw material allows for the internal transmission of light nearly in the same capacity as glass. Polycarbonate polymers are used to produce a variety of materials and are particularly useful when impact resistance and/or transparency are a product requirement (e.g. in bullet-proof glass). PC is commonly used for plastic lenses in eyewear, in medical devices, automotive components, protective gear, greenhouses, Digital Disks (CDs, DVDs, and Blu-ray), and sport helmets. Polycarbonate also has very good heat resistance and can be combined with flame retardant materials without significant material degradation. Polycarbonate plastics are engineering plastics in that they are typically used for more capable, robust materials such as in impact resistant “glass-like” surfaces. ...

HOW TO CHOOSE THE BEST CLIMBING HELMET WEAR-ABILITY What good does buying a  climbing helmet  do if you don’t wear it? Above all, pick a helmet that is comfortable and attractive in your eyes because if, on the other hand, you get an uncomfortable and unattractive helmet you will probably never wear it and it will do you no good.   PROTECTIVENESS Consider the type of climbing you’ll be doing. Are you at an increased risk of hitting your head or having something (e.g. rock, ice) fall onto your head? Or do you simply need a layer of cranium protection for the worst case scenario?   If your climbing helmet would be seeing lots of abuse then opt for a durable and more protective helmet. Otherwise, you might be able to get away with a lighter option.   Weight Weight can be an important criteria for gear selection depending on the type of climbing you’re doing. Those seeking to minimize climbing pack weight for whatever reason should look for...

EN12492 Impact / Shock Absorption Similar to both industrial  helmets  and bump caps, mountaineering helmets are subjected to an impact from a falling mass onto a fixed headform. However, to reflect the nature of the use, additional impacts are required at the front, side and rear of the helmet. These impacts are carried out by tilting the headform on the rigid base at an angle of 60° (so that impacts are carried out at 30° from the horizontal plane of the headform). Impacts are carried out using two strikers, one flat and one hemispherical, each weighing 5kg. Helmets are impacted using the hemispherical striker dropped from a height of 2 metres, and at the front, rear and sides using the flat striker dropped from a height of 500mm. In all cases, the transmitted force through the headform cannot exceed 10kN. Penetration As with industrial helmets and bump caps,  mountaineering helmet  are intended to provide protection against sharp / pointed objec...
